Cross section of a mature tropical cyclone. A typical tropical cyclone has an eye approximately 30–65 km (20–40 mi) across at the geometric center of the storm. The eye may be clear or have spotty low clouds (a clear eye), it may be filled with low-and mid-level clouds (a filled eye), or it may be obscured by the central dense overcast.
Concentric eyewalls seen in Typhoon Haima as it travels west across the Pacific Ocean.. In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones with maximum sustained winds greater than 33 m/s (64 kn; 119 km/h; 74 mph), or hurricane-force, and particularly in major hurricanes of Saffir–Simpson category 3 to 5.
Mesovortices visible in the eye of Hurricane Emilia in 1994. An eyewall mesovortex is a small-scale rotational feature found in an eyewall of an intense tropical cyclone. Eyewall mesovortices are similar, in principle, to small "suction vortices" often observed in multiple-vortex tornadoes. In these vortices, wind speed can be up to 10% higher ...
Hurricane Ian was a prolific lightning producer as it strengthened into a Category 5 hurricane on its approach to Florida. Storm chasers along the coast of Florida even witnessed cloud-to-ground ...
A Hurricane Hunters engineer captured video from inside Hurricane Helene's eye Wednesday after it formed along the Gulf of Mexico.
Milton completed an eyewall replacement cycle overnight Monday and the new eye quickly contracted down in size by almost half, Robbie Berg, one of the center’s hurricane specialists, wrote in an ...
The National Hurricane Center (NHC) anticipated on October 2 that strong upper-level winds would prevent any significant development of the system for at least a couple of days. [9] On the same day, a tropical wave – an elongated trough of low air pressure – tracked into the area.
Francine made landfall over the Louisiana coast as a Category 2 hurricane early ... could rise between 5 and 10 feet above ground levels, the hurricane center said. ... This anti-aging eye gel is ...
